Design Notes

This biobrick represents the DNA template for the transcription of a 65 nt shRNA, excluding the promoter. Trancription was performed with BBa_K3407023. The dsRNA sequence was taken from pUC57-OriLR-deGFP plasmid (BBa_K3407006). It corresponds to 27nt from the eGFP gene (nt 78 to 105), and is the one recognised and processed by Dicer to form siRNA. The shRNA has a single-stranded RNA (ssRNA) mutated loop region designed to deplete interaction with Fox-1 RBD (BBa_K3407004) [1], containing its C3U and G6A mutations “UGUAUAU” in Fox-1 RBD's RNA target sequence. The dsRNA region contains a GG overhang that would represent the overhang left when mini-3 (BBa_K3407002) cleaves a tshRNA (See iGEM TU Delft 2020, Design - Future perspectives), and that represents a good substrate to process the shRNA by Dicer into a siRNA.
